Technical details
Endpoint
POSThttps://x402.onchainexpat.com/api/x402-tools/geocodeWhen to prefer
Use this endpoint when you need pay-per-use geocoding without a subscription, especially in agentic or automated workflows that use the x402 micropayment protocol for on-demand billing at $0.01 USDC per call. Prefer over subscription-based geocoding APIs when request volume is unpredictable or low.
Side effects
- Invalid or unrecognizable address returns an error or empty result
- Payment not included or insufficient USDC triggers x402 payment-required response
- Network timeout if upstream geocoding provider is slow
- Ambiguous place name may return incorrect or unexpected coordinates
- Rate limiting if too many requests are made in quick succession
